Definitions

  • the present invention relates to a method for allowing a control of a vehicle provided with at least two wheels in case of puncture of a tyre.
  • a wheel for a two- or four-wheeled vehicle generally comprises a rim coupled with a tyre that is inflated to a given operating pressure.
  • Said tyre generally comprises a carcass structure having at least one carcass ply and at least one annular reinforcing structure associated with the carcass ply, a tread band of elastomer material applied to the carcass structure at a radially external position, a belt structure interposed between the carcass structure and the tread band and a pair of sidewalls at axially opposite positions on the carcass structure.
  • the tyre airtightness is ensured by the radially internal layer of said carcass structure generally referred to as "liner".
  • liner the radially internal layer of said carcass structure
  • pressure within the tyre decreases so that the vehicle's driver is forced to carry out a periodical restoration of said pressure.
  • Patent US 4,067,376 shows an alarm system connected with the pressure in a tyre which comprises a pressure-sensitive device susceptible of being mounted to the wheel and suitable to emit sonic or ultrasonic signals each time the inner pressure of the tyre exceeds a maximum value or is lower than a minimum value. Also shown is a system for automatically reintroducing the air lost by a tyre while a vehicle is running, to minimise the effects of a burst.
  • Manufacture of the wheel involves the presence of an integrated annular bag suitable to store an amount of compressed air under high pressure.
  • a safety pressure valve is placed between said bag and the tyre and is adapted to release air from the bag to the tyre each time pressure in the tyre goes down below a predetermined limit.
  • WO 03/057515 corresponding with the preamble of claim 38, A discloses a tyre and a pressure monitoring system mounted on an airplane.
  • the system operates in the pre-takeoff and pre-landing stages relates to a vehicle wheel assembly, comprising a pressurized-gas reservoir and elements for selectively connecting the pressurized-gas reservoir to the closed space.
  • the pressurized-gas reservoir is rotationally fixed to the wheel rim.
  • US 2002/104374 A1 relates to a method of maintaining the pressure within a test tyre installed on a vehicle being driven on multiple test runs to evaluate dynamic tyre performance.
  • a test tyre installed on a vehicle being driven on multiple test runs to evaluate dynamic tyre performance.
  • the adjustment is performed by releasing fluid from the tire opening a solenoid valve to bleed air from the tyre.
  • FR-A-2 822 414 relates to a wheel and a tyre pressure monitor.
  • the wheel comprises: a tyre with an outer envelope mounted on the rim, an inner envelope at the base of the rim to form a reserve of pressurized air, and an actuator to allow passage of air from the inner envelope to the outer.
  • a second actuator in the external envelope allows its deflation.
  • US 5 895 846 A discloses a method of processing signals in a system for monitoring tyres of a vehicle during travel, the system providing for each tyre a measurement which is characteristic of the condition of inflation of the tyre, in which: based on measurements carried out substantially at the same time, the measurement characteristic of one tyre is compared with the same measurement of at least one other tyre, the result of this comparison is periodically recorded so as to obtain a series of values, an alarm is given off when the variation in time of this series of values satisfies a predetermined relationship.
  • D5 ( EP-A-1 319 530 ), corresponding with the preamble of claims 1 and 16 respectively, discloses a fluctuation warning unit for issuing a warning when fluctuations of the tyre pressure per unit time exceed a predetermined threshold fluctuation, and a detected value warning unit for issuing a warning when a detected value of the tyre pressure is fallen to a value below a predetermined threshold detected value are provided.
  • this aspect is of vital importance for the rider's safety because due to the particular dynamics of this vehicle, the rider can become acquainted with such a situation too late.
  • tyres for two-wheeled vehicles are distinguishable for their marked transverse curvature.
  • This transverse curvature is usually defined by the particular value of the ratio of the distance between the radially outer point of the tread and the line passing through the laterally opposite extremities of the tread itself measured on the equatorial plane of the tyre, to the distance measured along the tyre chord between said extremities.
  • the value of the curvature ratio is generally not lower than 0.15 and is normally in the order of about 0.3 for rear tyres, but also higher, until about 0.45, for front tyres, against a value usually in the order of about 0.05 in tyres for motor-vehicles.
  • the Applicant has found that it is possible to ensure a safe stopping of the vehicle in case of puncture of a tyre by arranging a system for pressure recovery on the wheel and supplying the driver with an alarm signal informing of the puncture in progress, through measurement of the pressure variation internally of the tyre in the time unit.
  • the invention relates to a method of allowing a control on a vehicle with at least two-wheels in case of puncture of a tyre, each wheel comprising a rim and a tyre associated therewith, said method comprising the steps of:
  • said vehicle is a two-wheeled vehicle and said rim associated with said tank belongs to the front wheel.
  • said vehicle is a two-wheeled vehicle and said rim associated with said tank belongs to the rear wheel.
  • said method comprises the step of interrupting said communication between said tyre and tank when the inner pressure of said tyre is substantially the same as said operating pressure.
  • said method comprises the step of generating an alarm signal when the pressure of the fluid contained in said tank is lower than a predetermined second threshold value.
  • the invention relates to a vehicle having at least two wheels, comprising:
  • said tank is integrated into said rim.
  • said tank is operatively associated with a pressure sensor to measure the pressure of said fluid contained in said tank.
  • said pressure sensor is operatively associated with said signal generator to generate an alarm signal when the pressure of the fluid contained in the tank is under a predetermined second threshold value.
  • said valve is a solenoid valve.
  • said pressure sensor measuring the inner pressure of the tyre controls said communication between said tank and tyre by said solenoid valve.
  • said solenoid valve is operatively associated with said signal generator to bring said tyre into communication with said tank, when the inner-pressure variation corresponds to a reduction and is higher than a predetermined value.
  • a temperature sensor is provided which is operatively associated with said wheel to measure the inner temperature of the tyre.
  • said temperature sensor is operatively associated with said calculation unit to calculate, for each inner pressure measured according to said predetermined frequency at the inner temperature of the tyre, the pressure corresponding to a reference temperature (TR).
  • the invention relates to a wheel comprising:
  • each comparison between different pressure values (the pressure of the fluid in the tank and the inner pressure of the tyre, for example) is referred to the same reference temperature TR so as to make the comparison uniform, should pressures be measured at different temperatures.
  • Fig. 6 is a graph showing the pressure variation in time in case of puncture of a wheel of a four-wheeled vehicle in accordance with the invention and in a wheel of a four-wheeled vehicle of known type.
  • At least one wheel 1 for a two-wheeled vehicle in accordance with the invention and preferably at least one pair of driving wheels 1 for a four-wheeled vehicle ( Figs. 3, 4 ) in accordance with the invention, comprise a rim 2 on which a tyre 3 of an inner volume 3' is mounted.
  • a tank 4 suitable to hold a fluid under pressure, said fluid being air or a substantially inert gas such as nitrogen, for example.
  • the ratio between the operating pressure PE of the tyre 3 and a first pressure PP existing in said full-load tank 4 varies between about 0.1 and about 0.6, preferably between about 0.2 and about 0.4.
  • the ratio between the volume of said tank 4 and said inner volume 3' of the tyre is included between about 0.1 and about 0.4, preferably between about 0.12 and about 0.3.
  • the rim 2 preferably houses a valve 5 preferably at a radially inner position not far from the rotation centre of the wheel, which valve enables communication between the tank 4 and the inner volume 3' of the tyre 3 to be regulated.
  • Said communication can be obtained for example by providing the rim 2 with an internal duct 6 for connecting said valve 5 to the inner volume of said tyre 3, said valve 5 further providing a direct connection ( Fig. 2 ) or a connection through another duct 6' ( Fig. 4 ) with said tank 4.
  • Said valve 5 can be of the mechanical type or can be a solenoid valve fed from a power source present on the wheel or coming from the vehicle.
  • a pressure sensor 10 housed on the rim 2 or internally of the tyre 3, said pressure sensor 10 being operatively associated or associable with a calculation unit (not shown) preferably placed on the vehicle and capable of calculating pressure variations in the time unit.
  • calculation of said pressure variations is carried out with temperature compensation of same. More specifically, since the pressure of a gas is substantially proportional to the absolute temperature, a temperature variation causes a pressure variation that is not due to gas leaks or admissions from and to the tyre.
  • Said compensation preferably takes place in the following way: the calculation unit receives an information concerning pressure from the pressure sensor 10 and an information concerning temperature from a temperature sensor 11 (which is disposed on rim 2 or internally of tyre 3 as well, said temperature sensor 11 being operatively associated with said calculation unit); through subsequent application of the gas laws, the calculation unit draws the pressure value at said reference temperature TR. Then, calculated on these compensated pressure values are said pressure variations in the time unit, as shown in the following.
  • the pressure sensor 10 and temperature sensor 11 are integrated with each other.
  • the calculation unit is not on the vehicle, but is integrated with the pressure sensor 10.
  • the pressure sensor 10 carries out pressure measurement within the volume 3' of tyre 3 with a predetermined frequency F, this frequency being preferably included between about 0.05 Hz and about 50 Hz, and more preferably between about 0.1 Hz and 10 Hz, the Applicant considering the last-mentioned range a good compromise between the necessity to acquired data at the highest possible frequency and with a reduced energy consumption by the pressure sensor 10.
  • operatively associated with the calculation unit is a signal generator of the acoustic, electronic, lighted, digital or any other type capable of generating a signal at the moment the value of Vp is negative (i.e. there is a reduction in pressure Pi in the time unit), and overcomes a predetermined threshold value Vp* in absolute value.
  • Preferably said predetermined threshold value Vp* is included between about 0.005 bar/s and about 0.1 bar/s, and more preferably this value is included between about 0.01 bar/s and about 0.05 bar/s.
  • valve 5 follows a relatively simple operation scheme.
  • valve 5 if it is of the mechanical type, is calibrated in such a manner as to enable a fluid flow from tank 4 to the inner volume 3' until said value Vs* is overcome again by the inner pressure Pi.
  • valve 5 is a solenoid valve, the pressure sensor 10 or the signal generator associated with said pressure sensor 10 through the calculation unit, can send an opening signal and a possible closing signal depending on variations of Pi with respect to Vs* in the same manner as above illustrated.
  • Preferably said first threshold value Vs* is included between about 0.8 PE and about 0.95 PE.
  • Vs* In case of puncture, the value Vs* is likely to be no longer overcome by Pi because the fluid (air, for example) admitted from tank 4 is ultimately released to the outside, whereas in case of natural leakage of the fluid from the radially inner layer of tyre 3 the fluid flow from tank 4 is able to restore pressure PE thereby causing closure of valve 5.
  • valve 5 operation of same, as previously illustrated, will not be independent of the pressure sensor 10 as in the case of use of a mechanical valve, but will be actively determined by the detections carried out by said pressure sensor 10, through a signal generated by the sensor itself or through the signal generator.
  • said solenoid valve can be operated so as to be opened not only when Pi is lower than the first threshold value Vs* as above illustrated, but also by a signal sent by said signal generator when Vp corresponds to a reduction and exceeds the predetermined value Vp*.
  • tank 4 internally comprises a second pressure sensor 15 operatively associated or associable with said signal generator so as to generate a signal when pressure Ps of the fluid contained in tank 4 decreases under a second predetermined threshold value Vs**, said value being preferably included between about 1.5 PE and about 2.5 PE.
  • the signal generator in a further preferred embodiment of the invention, is operatively associated with a transmission system (not shown) preferably arranged onboard of the vehicle, which is capable of transmitting said signals to the driver's position, preferably by a pilot light associated with an acoustic signal.
  • a transmission system not shown
  • the method in accordance with the invention is preferably put into practice with the following modalities.
  • fluid preferably air
  • inflating valve 19 to a given room temperature, of 15, 20, 25°C or another value for example, that will correspond to said reference temperature TR.
  • Tyre 3 is first flat and therefore valve 5 connects tank 4 to the inner volume 3' of tyre 3.
  • valve 5 When pressure within the tyre reaches the prescribed operating pressure PE, valve 5 reaches its closed position preventing passage of air under pressure between tank 4 and the inner volume 3' of said tyre 3.
  • Tank 4 is then charged to said first pressure PP, generally included between about 8 and about 12 bars, more preferably between about 8.5 and about 10 bars.
  • valve 5 opens due to its calibration if it is of the mechanical type or to a signal sent by the pressure sensor 10 or said signal generator if valve 5 is a solenoid valve, until pressure Pi reaches the PE value again.
  • the first threshold value Vs* enables opening of valve 5 only after the Pi value has reached at least Vs*, i.e. a value included between about 0.8 PE and about 0.95 PE. In this manner steadiness to the wheel assembly is ensured since small recharges in case of minimum pressure losses are avoided.
  • the Pi value varies rather quickly in time at least until opening of said valve 5. Consequently the Pi variation in the time unit calculated as above illustrated by the calculation unit can overcome the limit of Vp* and in this case the signal generator is activated. Said signal generator generates a signal that is transmitted as an alarm signal to the vehicle's driver preferably in the form of a combination of a signal light on the dashboard and an acoustic signal.
